Bella Aqua Four Stage Slim Line Reverse Osmosis

STAGE 1: SEDIMENT FILTRATION

Sediment Filter:

Is designed to remove larger particles and sediment from the water before it enters the reverse osmosis membrane. 

During this first stage, water passes through a 1-micron polypropylene sediment filter, removing sediment, silts and mineral deposits preventing them from entering the reverse osmosis membrane.

Sediment filters are often made of polypropylene or cellulose materials.

Most systems require you to replace this sediment filter every 12 months!

STAGE 2: ONE MICRON ACTIVATED CARBON BLOCK

Consist of activated carbon that is tightly packed into a solid block. 

Activated carbon is known for its ability to adsorb impurities and contaminants such as chlorine, chloramines, volatile organic compounds (VOCs), pesticides, herbicides, and other dissolved organic compounds. 

STAGE 3: REVERSE OSMOSIS WATER FILTER

This is the most important stage of the reverse osmosis water filtration process. Water is forced through a tightly woven, semipermeable reverse osmosis membrane, filtering it from 1 micron to 0.0005 microns.

A reverse osmosis membrane is a thin film composite (TFC) membrane made of several polyamide layers. It allows only water molecules to pass through while rejecting dissolved salts, minerals, and other impurities. The process works by applying pressure to force water through the membrane, which is smaller than the impurities, so they get trapped on one side while pure water flows through to the other side.

The reverse osmosis membrane can effectively remove a wide range of impurities and contaminants, such as:

• dissolved salts, including sodium, calcium, and magnesium
• heavy metals such as lead, mercury, 
• bacteria, viruses, and microorganisms
• fluoride, chlorine and chloramines
• pesticides, herbicides, and other dissolved organic compounds

STAGE 4: REMINERALISER

During the reverse osmosis process, minerals and other dissolved solids are removed, along with impurities and contaminants. While this process results in clean and pure water, it also means that the water is “de-mineralised” and may lack some beneficial minerals in natural water sources.

This Filter stage adds minerals back into for a nice crispy taste
